It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a method, device and electronic equipment for generating a laser on-machine image of a photovoltaic silk-screen printing screen, which are respectively described below.

[0023] like Figure 1 As shown, the present invention provides a method for generating a laser machine image of a photovoltaic screen printing screen, comprising: S101, obtaining an original image of a photovoltaic silk-screen printing screen, and converting the original image into a standard image with a unified format and size; S102, generating a template drawing that meets the target process size based on the standard drawing; S103, obtaining a scanned image, and placing the elements in the template image into the scanned image to generate a laser machine image; wherein the scanned image is obtained by scanning a photovoltaic silk screen printing screen by a typesetter.

[0024] It can be understood that the original image refers to the dxf format drawing of the solar cell screen (i.e. photovoltaic silk screen screen). The dxf format is an open vector data format, which can be divided into two categories: ASCII format and binary format. The dxf format drawing is an AutoCAD drawing exchange file.

[0025] The standard drawing refers to the drawing obtained by removing elements such as dimensioning and text annotations from the original drawing; the standard drawing is a dxf format drawing that only retains the battery pattern.

[0026] The template drawing is a dxf drawing containing size information obtained after being modified according to the process parameters based on the standard drawing.

[0028] Scanned image: Since the wire mesh of the mesh is deformed, the area between the meshes is not a straight line, so a typesetter is needed to scan it. The scanned drawing is the scanned image.

[0029] Laser machine drawing: a DXF format drawing that guides the laser movement trajectory of the laser equipment.

[0030] Parsing software: An executable program written in C# with the following functions: 1.

[0033] It can be understood that both the scanned image and the template image are provided with external mark points, ie, external marking points. Aligning the external mark points on the scanned image with the external mark points on the template image can achieve alignment of the scanned image with the template image.

[0034] The number of external markers on the scanned image and the template image can be 2 or 4. If the number of external markers on the scanned image and the template image is 2, the two external markers are located on the left and right sides or the top and bottom sides of the image. If the number of external markers on the scanned image and the template image is 4, the four external markers are located in four different directions of the image.

[0035] In some embodiments, the elements in the template image include: at least one of: a grid line, a gradient line, a harpoon, a mark point, an anti-break grid, a border, and a chamfer.

[0036] In some embodiments, the original image is a drawing in dxf format, and the original image includes at least one element of a battery pattern, dimension marking, and text annotation.

[0037] In some embodiments, the typesetter scans the photovoltaic screen printing screen, including: The typesetting machine automatically identifies the scanning parameters and scans the photovoltaic screen printing screen based on the scanning parameters; The scanning parameters include the number of lines, line spacing and PT value (length of the screen) of the scanned image.

[0038] In some embodiments, the target process size includes at least one of a gate line size, a gradient size, a border size, a chamfer size, a harpoon size, an anti-break gate size, and a mark point size.

[0039] In some embodiments, the core steps of the method for generating a laser machine image of a photovoltaic screen printing screen provided by the present invention include: Step 1: Manually use analytical software to automatically convert the original image into a standard image with unified format and standard size; Step 2: After manually setting the process parameters using the analytical software, generate the template drawing (dxf format) and import it into the typesetting machine after verification; Step 3: The typesetter automatically identifies the scanned image parameters (number of lines, line spacing, PT value, etc.) and scans according to the parameters; Step 4: Align the scanned image with the external mark of the template image; then based on the scanned image, place various elements in the template image (grid lines, gradient lines, harpoons, mark points, anti-break grids, borders, chamfers) into the scanned image to generate a one-plate-one-image (laser machine image).

[0040] In summary, the present invention provides a method for generating a laser machine drawing for a photovoltaic silk-screen screen, comprising: obtaining an original image of the photovoltaic silk-screen screen, and converting the original image into a standard image with a unified format and size; generating a template image that meets the target process dimensions based on the standard image; obtaining a scanned image, and placing the elements in the template image into the scanned image to generate a laser machine drawing; wherein the scanned image is obtained by scanning the photovoltaic silk-screen screen with a typesetter.
